pTocZZwom z'meg/ concern) e f i Be it known that I, THOMAS PAXToN, acitizenofthe United States, and. a resident of the `city of Portland,county of MultnomaligState Aof Oregon,have .invented a cer- ...tainnewland useful Improvement in Fluid- Operated Turbine-Engines,ofwhichthe following isa speciiication.

The particulareobgect [of i to" provide an airl driven turbineespecially l iadapted `for `being used as the driving element 'of' ahand-guidedtoohsuch, for eN-A e ample, as a :planing tool; and to thisend so designing and building: turbine that the same will be` light solasto (be easily handled,

Vbut have sniicientpower toeiiciently do its work. p i e u 1 Some ofthefeatures bywhich I attain this result consist in sovarranging thecircumferential pockets `of the turbine that they `will widen invertical-plane toward the mouth, and when eXposedQtotheimp/act of the *jet ofthedrivingiiuid thev roof thereof isw inclinedM at suchangle as tto AAp resent an effectivefsurfacetqsaid.jet Ialso provide a pluralityof ,inlet ports, distributed equidistantabout the .eircumference of therotor;

and .with;' the'se, features I ,combine others which will hereinafterbefully described. i

lMy. invention `is .fully illustrated rin e the accompanyingdrawingsnwhich:

the driving direction. Ball bearings f areV faces, as

u cent pocket. `The pockets are therefore given a V-shaped form, or, inother words, enlargedtoward the mouth `in longitudinal sectin. W' mw,

`Thejnlet ports h in the bushingvg are formed as follows:"l `aking atangential line fz/ (Figp), an angular line y is drawn at Y therefrom,and describes the parallel faces of the roof and floor of the inletport.

rBythis construction, when `a pocket is brought into registration withaninlet port, the former willlbe so relatively arranged as to expose thesurfacerof its roof at an `inclinationtoU the jet of driving fluid, andin this way render the impact of the latter more efficient.' There areva plurality `of fluid inlet ports 7L (the drawing showingl eight)distributed equi-distant about the periphery of the motor. Asmanypockets 'are formed in e the .periphery of the motor as can beconveniently accommodated.

Thefluid' chamber ofthe twosides of the Qcasing. are connected by apassageway la, which is connected at 7271 with a; source of motorfluidAs shown in Fig. 1,fthe passageway 7c' may be conveniently'inade of acasting'screwed in place as shown in Figs. landt. 1 y

Zr designates the blades of the cutter-head secured in placeV byscrew-:bolts m. For the safety ofthe operator the cutterf'head isinclosedby a'pcover" made; of sections van',

dial lugs a of the cutter-head, as shown in The' cutterhead is:supported Ion indes pendently adjustable shoes Ao, p, located, re#

of rotation of the cutter-head. The rear cuti hinged together at a2 andscrewed to the ra-` l spectiVely, rearward and forwardof the anisterhead comprises side plates between which is secured a block of wood02, serving as the bearing member. The sides are cut away, as at o3, soas to expose the knives passing such point. The front ends of the sidesof the rear shoe extend to the front of the case sides of the turbine,and are hinged ona transverse shaft g. Slots o4g are provided in therear portions of the sides, as shown in Fig. l,

and through such slots extend a transverse Y shaft or clamping screwbolt 7', a nut rbeextended to such length asl to c ounter-balance theweight of the cutter-head. The extended part of the block 02 is providedwith a hand-grip t, as on the ordinary plane.

By thescrew 1" the' cutter-head may be adjusted relatively totherinitialrough work which the `knives are to d0. When this Work hasbeen accomplished the rear shoe is readjusted, as shown in Fig. 1. Thefront `shoe` p is 'depended upon `to determine the depth ofthe cut ofthe knives in the finishing work, also to allow for the wearof theknives. The front shoe cornprisesthe sides p', connected at the lowerend by a transverse web p?, serving as a bearingUY face.-` The sides pare provided with'slots p3, in which bear pins fu, and portions arecutaway, as at p4, in which bears the cam g on the transverse shaft g.One end of the latter is provided with a milled head bywhichV to rotateit and thereby adjust the front shoe as desired. The other end qf thecam shaft g is provided with a milled nut g2 by which the cam shaft maybe yclamped in place as adjusted. Since the forward ends of the sides ofthe rear shaft pivot on the cam shaft g, the axis of which is parallelto the axis of rotation of the cutterhead, the bearing face of the rearshoe is always maintained square with the roof, and

a cut sured'.`

The features shown and described regarding thel shoe, by which theplaner shoe is of uniform depth by the knife is asy supported on 4thework are also my invention,

and form the subject matter of Letters Patent'filed simultaneously withthis application.
